Internal investigations not only clarify the facts but also affect future investigation and litigation risks. The scope, procedures, and documentation methods of investigations must be designed with fairness and defense rights in mind. Evidence collection and interviews must also be reviewed for legal issues as well as personal information and labor concerns. A consistent roadmap is needed through disciplinary action, institutional improvements, and recurrence prevention measures based on investigation results. LIN's Investigation Response team provides one-stop support from investigation design through follow-up measures.
